Office, change default account tied to E3 subscription

I had to delete an Office E3 account and create a different one (still E3). In windows server 2016, in any Office application, even though I disconnect the old account to which the subscription was tied and reconnect with the newly created account, once the application is closed and reopened, the old account still shows up on top right of the window (with a yellow triangle).

To be specific, I have 3 users with their respective E3 subs working with remote desktop on that server. I'm using local profiles (non-Microsoft account).
